This AC Schnitzer-tuned BMW M5 looks like a real bully and gets even more power

The new frock is more than just for show: how does 799bhp sound?

Published: 21 Jul 2025

AC Schnitzer is one of those tuners that rarely takes things over the top, and this new upgrade package for both the M5 saloon (G90) and estate (G99) is a testament to that... despite now having more power than the super-focused McLaren 765LT. No seriously, it isn't over the top.

Because that 4.4-litre twin-turbo hybrid V8 develops 799bhp, up from 727bhp. Barely 72 horsepower! That's a really good sneeze! And while ACS hasn't specified any torque or acceleration improvements, the M5 already has plenty of both: the standard car currently serves up 737lb ft and a 0-62mph time of 3.5s.

So, bit more power. Lot more grrr. Complementing all that shiny new force is a lean, mean aero kit and rear wing attached to that bulged body; a bit like equipping a polar bear with cycling spandex shorts and streamlined goggles. Those claw-like canards on the front make a pretty strong statement too.

Other changes include 110mm stainless steel exhausts to add a little more expression to the M5’s voice, tweaked suspension that drops the ride height by 20mm, and ‘AC6’ lightweight forged alloys. Given the intricate detailing on the latter, any and every kerb on the road will probably warrant a clench.

AC Schnitzer will also make a handful of changes inside, revising the iDrive controller, footrest and pedals in machined aluminium, while throwing in some bespoke badges.

Pricing is yet to be announced since the package is still under development, but that should give you some time to find £111k for the base saloon - or another £2k if you want the Touring.
